Industrial Waste Water Applications

Vacom successfully treats oily wastewater and complex industrial wastewater in the metals processing and manufacturing industries.

There is a myriad of applications where Vacom provides best of class management of industrial wastewater.

Several applications are:
Metals Processing and Manufacturing

Eaton, YKK, Lockheed-Martin, and Caterpillar

Vacom successfully treats oily wastewater and complex industrial wastewater in the metals processing and manufacturing industries.
Customers such as Eaton, YKK, Lockheed-Martin, Caterpillar and many others have used the Vacom System™ to manage their highly complex oily wastewater generated from the manufacture of metal parts. Machine tool oils, heavy metals, suspended solids, phosphates, surfactants, and rust inhibitors such as Amines are removed and treated in a single step Vacom system. The result is clean water and a high BTU concentrate with oil contents ranging from 60-80% capable for reuse in a waste fuels program. The result is waste with value rather than the generation of hazardous waste with high disposal costs.

Consider the number and types of plants:
Steel Manufacturing: USA 23 plants
Metal Working (electronic components and parts): USA 10,000 plants

Chemical and Petro-Chemical Plants

Celanese Plant in Mexico

In large industrial plants most companies deploy physical/chemical treatment followed by biological treatment.

Wastewater streams are generated from multiple unit operations with wide and varied characteristics. There are always those streams that are high strength and highly complexed. These individual unit operation streams are easily identified as problematic and the cause of upsets in the wastewater treatment plant. At times they are so problematic that they are hauled offsite for disposal at a very high cost.

For example, at a Celanese Plant in Mexico, highly emulsified waste finish oil generated from the lubrication of Spinnerets used to extrude polyester fiber caused constant upsets in their large biological extended aeration treatment basins. A Vacom system was installed to treat the emulsified oily waste stream. The oils were concentrated and recovered as a fuel, the clean water was recycled as cooling tower makeup, and the larger wastewater treatment plant was restored to good working order.

Textile Industry

Georgia Institute of Technology

Vacom has worked closely with the Textile Engineering Department at the Georgia Institute of Technology to prove up our technology for recovering valuable Poly-Vinyl Alcohol (PVA) used to strengthen and size cotton fibers in the weaving process. Typically, PVA is washed off the fiber later in the process and is a major contributor to the load on biological wastewater treatment. The value of the recovered PVA pays for a Vacom system in short order.

The Vacom system can also be deployed to remove color compounds and heavy metals.
